Eco-house of straw

Articles about real estate | Eco-house of straw
Most of the people in Belarus, Russia and other countries is very cautious about the use of chemicals in food and drink - preservatives, emulsifiers, dyes, antioxidants and other supplements, although buying victuals, without reading, as a rule, the UPA forging its composition. People are very active in protesting against the use of agricultural chemicals - herbicides, pesticides, defoliants, insecticides, and even fertilizers.

All together advocate "environmentally friendly" products, constantly talking about it, but almost nobody really knows what it really is and how it differs from the "dirty".

For mass deployment of artificial, ie, obtained by chemical means, substances in the category of things people are already accustomed to and do not protest, relying, apparently, that would be able to make the right choice for yourself. Therefore, far fewer people control the quality of their "second skin" - clothes, shoes, accessories, and other wearing apparel, meticulously sorting out the share of synthetics in them and trying to find items with a predominance of natural ingredients.
It may seem incredible, but the same people who tend not to let "synthetic" in your everyday life, do not reflect on the fact that their home to a large extent represents the same "synthetic", ie, the product of a chemical revolution.

When buying clothes or shoes, we try to choose those instances in which there any "synthetic" smaller is not going into the differences between the types of synthetic substances, then, building or updating their home, often do not even wonder about the composition and origin of certain elements of the house.
Selecting a suit by the criterion of natural fabrics, we do not usually think about on turalnosti lining, not to mention the material of thread, buttons and other stock. In the case of housing this lightweight approach is unacceptable, if only because that arrays and surface elements, and hence the flow of influence is many times more.

Those who have asked similar questions, usually comfort themselves that everything will be fine, if the basic material of house will be brick or wood, do not arouse suspicion because of its centuries-long trial. But they forget that even 60-70 years ago, thinner beam 40 cm in diameter was not used in residential construction because of the large heat loss (and now find a log - a problem) and that in such a complex system like a house, there are other materials, the effect of which can not be compensated by walls of brick or wood.
In even less about the environmental performance of materials that make up the building, unfortunately, take care planners and builders. The reason is clear - not for yourself. Even today, when you can choose and buy different in terms of ecological materials, neodymium nokratno had seen a picture of construction "elite" house "elite" area in which the brick veneer exterior walls, and inside lay the insulation of the phenol-rezolnogo foam or some other equally malicious polymer.

Natural Alternative
Have you seen near the nest of birds, the creation of a swallow or wasps? It is perfectly adapted to the environment, weather conditions, the rhythm of life and the natural cycling home, have a close connection with nature and the cosmos. Can I use some techniques for building homes of birds and wasps in the human habitation?
Building a house out of straw bales may seem at first glance a crazy idea. But it is well known that the straw bales combine all the qualities of a magnificent building material: they are cheap, durable, easily accessible, environmentally friendly and have good insulation. Bales of straw are durable, yet protected from penetration and increasing humidity. Their insulating properties are much better than the wooden or brick walls. Straw block with normal thickness of 50 cm shows the excellent insulating properties, which after the application of plaster improved. Moreover, the wall is "breathing" order of magnitude higher than the wall of the natural logs. The thick walls with their peculiar structural surfaces have a special charm.

Living and breathing structures create an unusual climate in the room and radiate confidence and security. Rigorous rectangular surface and the smooth walls of straw blocks, too, can create, but it will require more skill and effort. They are not characteristic of the natural material. Houses of straw cubes, on the contrary, will be pleasing to the eye, delight soft lines. The round shape is also possible, if the "bend" a layer of blocks. Niches or round-arched windows and doors are made using conventional saws, just cut out the straw shape. Although if the owner tends to be flat planes and right angles - no problem too ...

The draft is based on the principle of eco consistency of the theory of sustainable development - development which meet the needs of the current generation without compromising the ability to meet the needs of future generations. The ecological imperative is included in the project concept as a dominant component.

The project, in addition to general R EQUIREMENTS assignment is based on the following provisions:
- Planning and volumetric solutions must take into account terrain, building technologies and to maximize the environmental quality of environment - internal and external - at minimal cost;
- House and land constitute a single artificial ecosystem that will not harm the environment and health of present and future generations;
- Total consumption of energy (especially fossil fuel energy) in the process of construction and the operation of buildings should be minimal;
- Maximum use of local eco-friendly materials, and maintenance of local flora and fauna;
- Socialization of habitat.

Planning for the territory, bearing in mind the principles of passive "solar" architecture and was aimed at the socialization of the territory, the development of friendly human environment, which should be "small homeland" for the present and next generations of eco.
This dictated the planning decisions of the territory and "solar" architecture structures: a straw house can be provided for a small pool and sauna (at the request of tenants), fireplace. Eco-house can be equipped with local low-cost permakulturnymi household sewage disposal systems, which enhance the fertility of the gardens and worked in the climatic conditions of Belarus.

Straw eco running, usually energopassivnym: building envelope are the drag coefficient of heat transmission at least 8 (modern SNiPs require 2.5) apply only to local eco-friendly natural materials (straw blocks right after balers), which is good impact on cost performance . During the construction of eco not used earth moving and lifting devices, as well as the walls are light and do not require a large amount of concrete in the foundation that will preserve the grass cover and not injure the land that our forefathers (and not without reason) "alive". Eco-house built using the already well established in Belarus ecotechnologies walling construction (plaster or plasterboard wall is covered with straw blocks) in the Frame option (load is timbered wooden frame).

This technology provides the following options:

Energy data
- Reducing energy consumption during construction as compared with kripichnymi / silicate protecting designs with modern heaters for 1 m2 of total area of at least 300 times.
The coefficients of thermal conductivity walling
indicator of sex without heating - 0,23 W/m2K,
indicator straw walls - 0,12 W/m2K,
indicator of the roof - 0,19 W/m2K.
The need for energy for heating - less than 40 kWh ch/m2 year.
High fire safety (after plastering) confirmed the official tests. The construction of the wall plastered straw was formally tested in the United States, attributed to limiting the class of fire-resistant F119 (metallic farm, for example, belongs to a class F15, ie, loses load carrying capacity in 15 minutes after exposure to open fire).
Construction period: since the start of excavation works (foundation) until the settlement is about 14 weeks if the building is being rhythmically.
The construction cost is about 260 u.e/m2 total area to finish "under the wallpaper" in the base version.

Experience with
In Belarus, the first eco village of straw blocks were built in 1996 In 1999, after official testing Minstroyarchitecture RB recommended that these projects are eco-houses to re-use. Their construction is continuing in increasing quantities, and, having begun as the construction of "housing for the poor" has turned into housing for the middle class and intelligent rich. " This part of the population today, concerned about the environmental quality of the dwelling (the problems of health impact polystyrene, PVC, fenolformaldegida, etc.) and the cost of heating: by 2007 Russia will pass on the price of European Union energy supplies in connection with WTO accession. This means that the price of gas will increase many times. On heating it is 1 m 2 straw eco-houses is spent in 3 times less energy, as evidenced by the practice ...
All necessary regulatory and technical documentation is available. Developers for the first time in the history of the CIS awarded the International Prize for energy efficiency and sustainable energy in the category "Housing" (Austria, 2000), nominated for UN-Habitat and a number of other prestigious international awards. A number of foreign specialists, including German, Latvian, Lithuanian, Russian, Ukrainian, requested and received in 2003-2004. This environmental technology education in Belarus. Note: we are not - they have, and they - we have.

Finally, the last thing: the Bible know that the wise Solomon of the masters, who "knew how to chop wood, he gave several cities. Why? Izoterikam know that if you break someone else's life (eg, wood) to create items that meet your needs, then these objects have a certain quality of energy, and you are the karmic responsibility. Mastery tree felling in ancient times was the reduction and removal of karmic responsibility and improving the energy tree, which affected the energy built homes. It is well-known masters of feng shui. Now this knowledge is practically lost. At best, they'll tell you that the forest must be prepared in the winter and at a certain phase of the moon ... is another matter - straw: the plant has passed a full cycle of development, energy, stem - a powerful and positive, specific skills in the procurement is not required, and energy in the house turns out great. This highlights all who live in eco-homes out of straw.

For example, residents of Ecovillage "Friendly" thatched house called "living" and noted that they had "good sleep". Probably why the area under the foundations of ancient religious and defensive structures, such as the pyramids of Giza or the Great Wall of China, lined with a thin layer of straw. Previously Belarusians also used the power of straw: straw to create spiders that are attached over the baby cradle and protect children from "evil forces", thatched roofs, mats, utensils, etc. So why is today, in a difficult economic situation, not use this easy, cheap, energy-efficient, environmentally friendly material and does not get much higher quality of individual homes for far less money?
